When it’s back, everyone knows in 60 seconds.
Stock lands, Stem goes off: email, SMS, WhatsApp and push from one queue, in waves, never twice.
Try it: restock the overshirt and watch the waves go out.
Then watch it sell. Again.
Every alert carries a code, so you see exactly which sales came back. Take pre-orders before stock lands.
- Revenue attribution you can trust, 7-day window
- Full payment, deposits or pay later, through your Shopify checkout

Quick questions
Everything else is in the FAQ.
Will WaitCherry slow down my store?
No. The storefront script is under 15 KB gzipped, loads with defer, makes no API call on page load, and only loads the form on sold-out variants. Our target is no more than a 1-point Lighthouse difference on mobile.
Do I need to edit my theme code?
No. WaitCherry is a Shopify theme app extension. You enable the app embed and add blocks in the theme editor. Uninstalling removes everything cleanly.
What counts as a notification?
One notification is one back-in-stock, pre-order, reminder, price-drop or low-stock message sent to one subscriber. Confirmation emails, double opt-in emails, test emails, reports to you and web push are not counted. SMS and WhatsApp use credits instead.
What happens when I reach my limit?
You get a warning at 80%. At 100%, monthly plans with overage on keep sending at $1 per 250 extra notifications, up to a cap you approve. Otherwise messages queue until you upgrade or the period resets. Signups never stop.
